Swarm cases

receipt 10041: HAS2 in dopamine neurons, braak

power
full sample -0.14 (p 0.573, n 18), 95% CI -0.57 to +0.35. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.14 (p 0.573, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.18 (p 0.465, n 18). could be the mix.
skeptic
leave-one-out range -0.31 to -0.05, sign flips 0; without severely affected donors -0.14 (p 0.573, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for HAS2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 10040: HAS2 in oligodendrocytes, braak

power
full sample +0.08 (p 0.767, n 18), 95% CI -0.41 to +0.52. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.12 (p 0.640, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.03 (p 0.922, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.21, sign flips 3; without severely affected donors +0.08 (p 0.767, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for HAS2 in oligodendrocytes.

case closed: nothing better to follow up.
